Noel Gallagher has ''albums worth'' of unheard Oasis tracks.

The 47-year-old musician revealed he is always writing music, so has a growing stockpile of material since 1993.

He revealed: ''Instead of writing 15 or 16 songs for a cycle of where [Oasis] were at, we were using five, but I was still writing 15, 20 songs, so there's loads of stuff left over from those days. Albums and albums worth of material.''

The guitarist-and-songwriter - who quit the band in 2009 - explained he has built up a huge collection of unheard tracks since the band's debut album 'Definitely Maybe', as he writes a minimum of 30 songs before entering the recording studio.

He said: ''I've had a stockpile of songs since 1993.

''I've never written for a specific project, I've never been in the studio with less than 30 songs. I've just recorded an album, but I've still got another 30 songs.''

This year there has been growing rumours about the band reforming, but the 'Don't Look Back In Anger' songwriter recently shut down reports of a reunion, saying he ''doesn't see the appeal'' of reconnecting with his brother and former bandmate Liam Gallagher.

However, the star did tease lots of the band's demos have been ''left behind'' during the making of their seven records.

Speaking to BBC Radio 4's 'Mastertapes', he added: ''Because you move so fast as a writer, and you can only really do ten songs on an album at a time, lots get left behind.''
